摘要:
A flow control apparatus and method for accurate detection of occlusion conditions in a feeding set. A sensor is arranged with respect to a pumping device to produce a signal indicative of pressure in the feeding set. A control circuit that may receive the sensor signal from the sensor indicative of the pressure in the feeding set may also control operation of the pumping device. The control circuit is configured to operate the pumping device in an operational state, and in a reset state subsequent to the operational state in which the pumping device does not produce a pumping action and the pumping device is moved to a position in which the pumping device does not block the feeding set to permit fluid flow in a backflow direction opposite to the patient direction thereby relieving any built up pressure in the feeding set downstream of the pumping device.
